I ,5. 6. /01am sitioned'as indicated by full lines in the drawings. The extension 5*ot' the overflow pipe is adjusted to any level necessaryto insure vending of the quantity of gasoline or ther liquid'that is'to be'sold in cXchange for the coin or check inserted in the apparatus. For

' example it the liquid is to be sold at 20 per gallon'and a 50 coin is used as the basis of eachsale' the extension is set so that two and one-half gallons of fluid will be. retained in the container 51 before the overflow begins.

The customer inserts a 50 piece into the coin chute 11 and this coin while rolling downwardly within the chute, comes against the strip .13 and lifts it so that arm 14 will'be moved to bring contact 15 against contact16. This-will place the electro-magnet 19 in'communication with the service line inasmuchas the contacts 27 and 28 are electrically COIlIlGCtGClflHCl the contacts 36 and 37 are also pressed together. Consequently magnet 19, being energized, will attract its armature and bring contact 22 against contact 23. After'the coin C passes out of the chute 11 the strip 13 will return to its nor- 7 mal position, thereby breaking .the electrical connectionat 15 and 16 but as the contacts 221 and 23' aretogetheiythe current through the electro-magnet will be maintained by way ofthese contacts with the result that thearmature will beheld to the magnet and current willflow from'the'wire 2 t'through the switch :25 t'othe' motorand thence back to the line by way of, wire 35.

As soon as the motor begins to operate, the pump cont-rolled thereby will elevate liquid to the container '1. The float 34 will be raised with the level ofthe liquid pumped intothe container 1 and is so .nection between 'the contact 27 and 28. :sequently the operation of-the motor will be .stop'ped'and'no further liquid will be pumped adjusted that when the level 'of this liquid reaches the top of the overflow extension 5 =theswitch contact 26, which has been moved by the rising of the float, will break the con- Coninto the container. The customer then places thehose 44 toathe inlet of the tank to'be filled and swings the valve arm llsoas to open the outlet valve 42. This action promptly breaks the electrical connection betwen I the contacts 36 and 27. isofcourse shifted automatically as soon as s the circuitltothe motor is broken by the float W Thespring actuated armature 2O switch and, therefore, the connection between the contacts 22 and 23 is broken at the same time that the motor is stopped. \Vhen the valve 4-2 is opened the liquid trapped in the container will flow outwardly and the operation is thus connilctcd.

it will be noted that an additional supply 0t liquid cannot be pumped into the container until the valve has been closed because this valve must be in closed position in order to insure a connection between the contacts 30 and 37. By providing: the valve switch the purchaser is prevented from placing the coin in the slot and immediately drawing gasoline from the container 1, thereby getting a greater quantity than he is entitled to receive. Should such an attempt be made the opening of the valve will innnediately break the circuit to the motor and the coin or check would. be lost to the customer.

It is to be understood of course that the switches located adjacent to the gas container are to be gas proof and that all wiring leading thereto is likewise to be contained within a gas proof conduit as shown, for example, at 46, a portion of this conduit of coursebeing extended to the motor and pump located in the housing 7 Suitable means for protecting the apparatus from the use of slugs, etc. can be provided as will be obvious.

\Vhat is claimed is:

1. The combination with a liquid container having an inlet and an outlet, and a valve for closing the outlet, of means including a motorfor directing'liquid into the container through the inlet, a float operated switch carried by the container and shiftable by liquid within the container for breaking the circuit to the motor when the liquid reaches a predetern'lined level in the container, said switch being norn'iallyclosed, a

normally open coin operated switch, a magneticswitch adapted to be energized and actuated by the closing of the coin controlled switch,thereby to close a circuit to the motor by way of the normally closed float controlled switch, said magnetic switch constituting meanstormaintaunng the circuit closed following the opening of the coin contnollcd switch. means controlled by the outlet valve for breaking the circuit to the motor when the valve is opened, and means for opening the magnetic switch when the circuit to the motor is broken by the float controlled switch or the valve controlled switch.

2. The con'ibination with a container having a valved out-let and means including a motor for directing liquid into the container, of an electric'cireuit extending to the motor and including a normally open. magnetic switch, a switch operated by the insertion of a coin for closing a circuit to the magnetic switch, thereby'to actuate said switch to close the circuit to the motor and maintain the switch. closed, means for breaking the circuit to the'motor, means controlled by the break- 1,71aese 3 ing of the circuit for opening the magnetic the container for opening the other switch. switch automatically, said circuit breaking In testimony that We claim the foregoing means including separate switches, means as our own, We have hereto aflixed our sig- 1 operated by the rise and fall of liquid in natures.
